download an entire directory using wget

I am trying to download the files for a project using wget as the SVN server for that project isn't running anymore and I am only able to access the files thorugh browser.
The base URLs for all the files is the same like -

-l1 //just download the directory (tzivi in your case)
-l2 //download the directory and all level 1 subfolders ('tzivi/something' but not 'tivizi/somthing/foo')
And so on. If you insert no -l option, wget will use -l 5 automatically.
If you insert a -l 0 you´ll download the whole internet, because wget will follow every link it finds.
